CULTIVATOR.

Specification of Letters Patent.

Application filed. May 10, 1912. Serial No. 696,510.

To all whom it may concern Be it known that I, WVILLIAM P. MoRRow, acitizen of the United States, residing at Woodward, in the county ofWVoodward and State of Oklahoma, have invented a new and usefulCultivator, of which the following is a specification.

This invention relates to cultivators particularly designed for use incultivating listed corn or corn planted in furrows or ditches.

One of the objects of the present invention is to provide a. cultivatorof this type having supporting runners or the like designed to travel inthe furrow, there being means adjustably connected to the sides of saidrunners for directing the loosened soil either into or away from thefurrow.

A further object is to provide a machine of this character which can beused in the cultivation of various kinds of growing crops and which canalso be used for pulverizing, leveling and packing the soil, there beingmeans combined with the machine for cutting off grass and weeds.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a plan view of the machine. Fig. 2 is aside elevation thereof. Fig. 3 is a bottom plan view. Fig. 1 is asection on line A-B Fig. 1.

Referring to the figures by characters of reference 1 designatesparallel runners having front and rear brackets 2 on the outer facesthereof within which are slidably mounted the downwardly extending sideportions of arches 3. These arches are supported perpendicularly to therunners and each arch is preferably formed of two sections having theirupper ends lapped and bolted together, as shown at L. A beam 5 issupported by the arches and a seat 6 for the driver is mounted thereon.

-end of a brace bar 15.

The lower ends of the arches 3 are bent rcarwardly, as shown at 7 so asto project through eyes 8 upstanding from the inner sides of cultivatorsections 9. Each of these sections is preferably made u of asubstantially oblong body having tat upper and lower faces, the frontend of the body being upturned, as shown at 10, so as to ride easilyover the soil contacted thereby. Series of soil engaging blades 11 aresecured to'the lower face of eachbody portion 9, the blades of eachseries being preferably formed of angle strips parallel to each otherand arranged diagonally upon the lower face of the body portion, asshown particularly in Fig. 3. Preferably two of these series areemployed although it is to be understood that any desired number of themmay be used. The blades of both series on the body are disposed alongparallel lines and each blade is detachably connected to the bodyportion 9 by means of bolts 12 or the like. A bracket 13 is secured uponthe middle portion of each of the body portions 9, and is connected, bymeans of a link 14, to one The bars 15 of the two sections are crossedand each of them has a series of apertures 16 therein any one of whichis adapted to receive a threaded bolt 17 extending from a bracket 18depending from beam 5. Thus it will be seen that the bars 15 can besecurely held relative to the beam 5 and the sections 9 held in properpositions relative to the runners.

As shown particularly in Fig. 2, the front ends of the soil engagingblades 11 are inclined upwardly and forwardly as at 19 and it will alsobe seen, in said figure, that the front ends of the runners 1 are curvedupwardly and forwardly so that the parts will thus ride easily over thesoil engaged there by. Brackets 20 are connected to the centers of thefront ends of the body portions 9 of the cultivator and draft devices 21are adapted to be connected to these brackets. Eyes 22 extend from thebody portions 9 at the sides opposite those from which the eyes 8extend.

It will be apparent that when the parts are arranged as shown in thedrawings, the machine, when drawn along a furrow, with the runners 1traveling within the furrow, will engage the soil and draw it into thefurrow, the blades 11 performing this operation. At the same time anygrass or weeds which may be growing at the sides of the furrow will becut off by sharpened blades or knives 22 which extend laterally andrearwardly from the front end portions of the runners 1 and under thesections 9. These blades are adjustably and detachably connected to therunners preferably by means of U-bolts 28 extending through the runnersand which straddle arms 24 formed integral with and extending rearwardlyfrom the inner ends of the blades. During the operation of the machinethe weight of the driver is transmitted, through beam 5 and arches 3, tothe sections 9 and the blades 11 are thus caused to bite into the soiland not only shift it toward the furrow, when the parts are arranged asin Fig. 3, but also to pulverize and to pack the soil. The weight of thedriver is furthermore transferred to the sections 9 by the braces 15.

Should it be desired to use the machine for shifting the soil away fromthe furrow, it is merely necessary to transpose the sections 9 so thatthe eyes 22 will be engaged by the rearwardly extending end portions 7of the arches.

It is to be understood that if desired, the runners 1 can be dispensedwith and the arches removed from engagement with the sections 9 afterwhich said sections can be connected together by placing the eyes 8 ofone section in alinement with the eyes 8 of the other section and thenrunning a rod through the eyes which serves to pivotally connect them. Anumber of sections can thus be connected and the resultant struc-- tureused as a harrow or pulverizer.

What is claimed is 1. A cultivator including spaced soil engagingsupporting means, a connection therebetween, and oppositely disposedsections hingedly connected to the respective supporting means, eachsection including a body portion and separate rows of parallel blades.secured to the lower face of the body portion, the blades of all of therows being parallel and one of said rows being arranged in front of theother row, all of the blades having substantially horizontal obliquelydisposed soil engaging edges.

2. A cultivator including spaced soil engaging supporting means, aconnection therebetween, and oppositely disposed sections hingedlyconnected to the respective supporting means each section including abody portion and separate rows of parallel blades secured to the lowerface of the body portion, the blades of all of the rows being paralleland one of said rows being arranged in front of the other row, all ofthe blades having substantially horizontal obliquely disposed soilengaging edges, and means for adjusting the body portion angularly withrespect to the soil engaging supporting means.

3. A cultivator including connected sections each including a body and aseries of soil engaging blades upon the lower face of the body, saidblades being obliquely disposed, the blades on one section convergingtoward the blades on the other section, and a soil engaging structure.

l. A cultivator including connected runners, means carried thereby forsupporting a seat, sections hingedly connected to the respective runnersand extending in opposite directions therefrom, each section including abody portion, and obliquely disposed soil engaging blades upon the lowersurface of the body portion, all of said blades being parallel andhaving their active edges substantially horizontal, and means foradjusting the sections angularly upwardly and downwardly with relationto the runners.

5. A cultivator including a soil engaging seat supporting structure,interchangeable sections hingedly and detachably connected to thestructure, each section including a body portion having an upturnedfront end, and a series of parallel blades extending downwardly from thebody portion and having their front ends inclined upwardly andforwardly, the blades on each section being obliquely disposed andconverging toward the blades on the opposed section.

6. A cultivator including a central soil engaging structure,interchangeable sections hingedly and detachably connected to thestructure, each section including a body portion having an upturnedfront end, and a series of parallel blades extending downwardly from thebody portion and having their front ends inclined upwardly andforwardly, the blades on each section being obliquely disposed andconverging toward the blades on the opposed section, and draft devicesconnected to the front end portions of the sections.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
